Red services are shrinking year-on-year, green growing. And there's a few areas left out - YouTube, whose music videos create a box three times the size of everything put together; iTunes can't count because it's not a website; and MySpace because it's impossible to quantify which parts of the MySpace traffic is heading there for music.

Interesting things to note includes that Last FM has seen an uptick - despite having become a lot less flexible in how you can listen; AOL and eMusic have also grown audience in difficult years, and the figures here suggest that MOG is in the sort of decline that content points to.
